LM35 Temperature sensor

The LM35 temperature sensor outputs an analog voltage (a varying DC voltage that rises linearly with temperature) directly readable on any Arduino or ESP32 analog pin. The lm35 temperature sensor arduino connection requires no calibration circuit — just power it at 4V to 30V and read the ADC value. It covers a temperature range of -55°C to 150°C, giving it far wider coverage than most beginner sensors.

One non-obvious technical detail is that the LM35 outputs exactly 10mV per degree Celsius, so at 25°C the output is 250mV. The limitation is that reading temperatures below 0°C requires a small offset resistor in the circuit, which many beginners miss. Students and engineers for weather stations, thermal monitors, and remote sensing builds. Connect VCC to 5V, GND to ground, and read the analog output pin. StemVolt provides this sensor with trusted quality, ensuring reliable performance and easy usability.
